Cannot connect with SSH to newly booted VM
The provisioning and booting process may take as long as five minutes in some cases, depending on the specific operating system you are selecting.
Note that if you selected an image marked "ISO" when provisioning the VM, you will have to install the operating system via VNC. If you simply want a ready-made VM up and running, you should select an image marked "template" instead.
I cannot ping my IP address 172.20.8.187
The IP address starting with 172 is the private IP address for your VM. Go to your VM details page and look for the "external IP address".
How to purchase the Special XYZ plan?
First, check https://dynamic.lunanode.com/info.php to make sure it is still in stock. If so, you can register an account and then go to the Create VM sidebar option to create the VM of your desired special plan. Note that special plans are only available for a limited time.
Do you support IPv6?
Currently we do not support IPv6. Our hardware is fully IPv6 ready and we have IPv6 allocation ready, we are waiting for next OpenStack release Kilo (estimated May 2015) to fully support IPv6 with prefix allocation.
My account request was denied
We do not accept new account registrations from proxies, hosting services, or other non-residential/business IP addresses. Please contact support@lunanode.com if you do not know why your account request was denied.
How to resize my VM?
To upgrade your VM, follow these steps:
- Snapshot your VM
- Provision a new VM from the snapshot with your desired plan
- Ensure new VM is functioning
- Detach the floating IP from both old and new VM
- Attach the old floating IP to the new VM
To downgrade, you will need to resize your disk. Contact support if you need assistance doing this.
Unable to attach volume to my Windows VM
Volumes are best used with Linux virtual machines using the virtio driver. If you are using another operating system or ide driver, then you likely will need to shut down the VM before attaching or detaching volumes. You may also need to specify the attachment target as /dev/hdc or /dev/hdd or etc.
I cannot login as root!
As stated in the "VM provisioned successfully" email, template-based virtual machines are configured to accept connections with the administrative user. The username and password are displayed on the virtual machine details page. For security reasons, the VM does not accept root login by default.
Once authenticated as the administrative user, you can execute sudo su to login as root.
If you wish, you can of course set a root password. First, login as root by authenticating with the administrative user and running sudo su. Then, run passwd to set a root user password. Finally, edit the SSH configuration:
sed -i 's/PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config service ssh restart; service sshd restart
Then logout and you should be able to authenicate via SSH directly as the root user with your newly set password.
Alternatively, you can use a startup script so that the root password is set when the VM boots.
Note: use an SSH client like Putty to authenticate.
Please note that our services are unmanaged and you are responsible or the security of your VM; if your VM is taken over and used in denial of service attacks, spam, or other activities that violate our terms of service, your account may be suspended depending on the circumstances.
